2002 – 2020 – Watts Up With That?

2002 – 2020 – Watts Up With That?

An excellent way to undermine Western economies is to render their power generation unreliable and expensive.  That objective of Green thinking is progressively being achieved by Government policies throughout the Western world, but without popular mandate.

The graphic below shows the progress that has been made in installing Weather Dependent Renewables in the UK to reach the status shown above according two the Renewable Energy foundation data.


This post uses installation and generated power output data from the UK Renewable Energy Foundation 2020 to track the progress of the UK Weather Dependent Renewables, (Wind and Solar), fleet of generators since 2002.  The use of that data to results in the following:

  • an assessment of  the Productivity / Capacity percentage, of the UK Renewable generation fleet since 2002, which has achieved an overall productivity of ~22%.  That productivity percentage may vary marginally on an annual basis as a result of Weather conditions.
  • in combination with summary comparative cost data from the US Energy Information Administration, (EIA), on different power generation technologies, (capital and long-term), it compares the bare capital costs and long-term probable future monetary commitments that are incurred by the 2020 UK fleet of Weather Dependent Renewables.
  • overall combined Weather Dependent Renewables are roughly 10 times the cost of using Gas-firing and about 1.5 times the capital cost and 2.5 times the long-term cost of Nuclear power for same nominal electrical power production.
  • as of end 2020 it assesses the estimated capital cost of the UK Weather Dependent Renewables fleet to be about 65£billion.
  • the UK 2020 Weather Dependent Renewables fleet would incur an estimated long-term cost commitment of about 274£billion.
  • the extreme costs of Solar Power in the UK when accounting for it’s low productivity / capacity percentage.
  • the high future cost commitments that are entailed in the mandating of Offshore power even when accounting for their better productivity / capacity percentage.
  • it estimates the maximum CO2 emissions savings achieved by the present UK Renewables fleet to be ~22 million tonnes.  This amounts to less than 6% of UK CO2 emissions, about 0.06% of 2019 Global CO2 emissions and about 4% of the 2020 growth of CO2 emissions from the developing world:

but, this averted emissions value does not account for the CO2 emissions and energy requirements involved in sourcing, manufacture and installation of the physical elements of Weather Dependent Renewable generators.

  • the additional CO2 emissions over Gas-firing for the same power output resulting from the use of overseas sourced Biomass, (nominally Carbon neutral, by policy), at the UK Drax power stations can be estimated to exceed the maximum potential 22 million tonnes of CO2 savings achieved by installing the UK fleet of Weather Dependent Renewables.


  • extreme financial damage and loss of Grid reliability is arising by the effective and politically pressurised elimination of UK and European Fracking technologies.  These have stopped access to indigenous Natural Gas for electricity generation both in the UK and throughout Europe.  These policies are only to the benefit of the sales of Russian controlled gas exports.

The progress of UK Weather Dependent Renewables since 2002

The Renewable Energy Foundation reports on Weather Dependent Renewables and Green energy in the UK.  It provides annual installation and output data from 2002 up to the end of 2020.  The time series Renewable Energy Foundation data of installations and power output is shown above.


And the growth in installations achieved for each technology year by year:

The progress of Weather Dependent power produced compared to their installed installations is shown below.

The three graphs above show the progress of Renewable installations in the UK since 2002 noting:

  • a massive commitment to poor productivity Solar PV Power 2012-2016, mainly induced by the influence of Liberal Democrats in government during that period.
  • Solar PV installations had virtually ceased in 2019.
  • Onshore Wind power installations were radically reduced in 2020
  • output from Offshore Wind farms overtook the output of UK Onshore Wind in 2020
  • a remarkable reduction from the previously enthusiastically deployed Weather Dependent Renewable installations by 2020.
